The motivation to participate in crowdsourcing (CS) platforms is an emerging challenge. Although researchers and practitioners have focused on crowd motivation in the past, the results obtained through such practices have not been satisfactory. Researchers have left unexplored research areas related to CS pillars, such as the evolution of the crowd’s primary motivations, seekers applying effective policies and incentives, platform design challenges and addressing task complexity using the synchronicity of the crowd. Researchers are now more inclined to address these issues by focusing on sustaining the crowd’s motivation; however, sustaining the crowd’s motivation has many challenges.

To fill this gap, this study conducted a systematic literature review (SLR) to investigate and map the challenges and factors affecting sustained motivation during CS with the overcoming implications. Studies that satisfied the inclusion criteria were published between 2010 and 2021.

Important sustainable factors are extracted using the grounded theory that has sustained participation and the factors' cohesion leads to the identification of challenges that the pillars of CS face. Crowds being the most vital part of CS contests face the challenge of engagement. The results reported the factors that affect the crowd’s primary and post-intentions, perceived value of incentives and social and communal interaction. Seekers face the challenge of knowledge and understanding; the results identify the reason behind the crowd’s demotivation and the impact of theories and factors on the crowd's psychological needs which helped in sustaining participation. Similarly, the platforms face the challenge of being successful and demanding, the results identify the latest technologies, designs and features that seekers proclaim and need the platforms designer's attention. The identified task challenges are completion and achievement; the authors have identified the impact of trait of task and solving mechanisms that have sustained participation.

The study identifies, explores and summarizes the challenges on CS pillars researchers are facing now to sustain contributions by keeping participants motivated during online campaigns. Similarly, the study highlights the implication to overcome the challenges by identifying and prioritizing the areas concerning sustainability through the adoption of innovative methods or policies that can guarantee sustained participation.

Explore the effects of competition policy on an important competitive dimension of digital platforms, namely quality.

The deterrence effect of competition policy should induce firms to compete on merits, with lower prices and higher quality for consumers. Deterrence, or the inducement not to infringe competition law, may depend on the harshness of penalties and/or the likelihood of conviction. We use competition policy indicators that are associated with these deterrence dimensions, allowing for non-linearities and interactions of the indicators. We use a unique data survey of digital gig platform users, that covers at least two dozen platforms and more than 50 countries. Quality is measured using multidimensional indicators of the level of satisfaction of platform users with different platform services. We control for platform user and country characteristics, including other regulatory indicators such as labor laws, to recover different effects.

Results suggest that competition policy is relevant for differences in product quality across platforms and countries. Important non-linearities are uncovered, where substantive rules of competition policy interact with competition authority power. The effects depend on either level of the indicators, suggesting that deterrence effects depend upon a combination of both law in the books and competition policy practice.

The estimates suggest a need to balance both dimension of deterrence, namely, strictness and effectiveness to expand the effects of competition policy on competition.

This is the first paper that explores the effect of competition policy on non-price or non-margin competition dimension. It is the first to study the effect on a sample of digital platforms. It contributes to the literature of deterrence effects of competition policy.

The investigation concentrated on studying a distinct category of tubular heat exchanger that uses swirling airflow over tube bundle maintained at constant heat flux. Swirl flow is achieved using a novel perforated baffle plate with rectangular openings and multiple adjustable opposite-oriented saw-tooth flow deflectors. These deflectors were strategically placed at the inlet of the heat exchanger to create a swirling flow downstream.

The custom-built axial flow heat exchanger consists of three baffle plates arranged longitudinally supporting tube bundle maintained at constant heat flux. The baffle plate equipped with saw-tooth flow deflector of various geometry represented by space height ratio(e/h). Next, ambient air was then directed over the tube bundle at varying Reynolds number and the effect of baffle spacing (PR), Space height ratio (e/h) and inclination angle(a) of deflectors on performance of heat exchanger was experimentally analyzed.

The heat transfer augmentation of heat exchanger for given operating condition is strongly dependent on geometry, inclination angle of deflector and baffle spacing.

An average improvement of 1.42 times in thermal enhancement factor was observed with inclination angle of 30°, space height ratio of 0.4 and a pitch ratio of 1.2 when compared to a heat exchanger without a baffle plate under similar operating conditions.

The heterogeneous character of Industry 4.0 opens opportunities for studies to understand the difficulties and challenges found in the transformation process of manufacturers. This article aims to present a critical analysis of the modernization process of an Industry 3.0 automated cell into a fully autonomous cell of Industry 4.0. The objective is to elucidate the difficulties found in this transition process and the possible ways to overcome the challenges, focusing on the management perspective.

For this, the needed steps for the technology transition were defined and the main I4.0 enabling technologies were applied, such as the application of machine learning algorithms to control quality parameters in milling.

The main challenges found were related to the obsolescence of the equipment present in the cell, challenges in data integration and communication protocols, in addition to the training of people who work actively in the project team. The difficulties faced were discussed based on similar studies in the literature and possible solutions for each challenge.

This understanding of possible barriers in the modernization process, and the step-by-step defined for this transition, can be important references for professionals working in manufacturing industries and researchers who aim to deepen their studies in this important and disruptive stage of world industrialization.

This study aims to investigate the factors that lead to the failure of some rewards to induce knowledge sharing behavior among employees, with much focus on employees’ attitudes and leadership’s knowledge of employees’ preferences, and presents a model that depicts the linkages.

To investigate why the provision of some rewards fails to induce knowledge sharing behavior among employees, this study uses the preferred reporting items for systematic reviews and meta-analyses framework to identify and analyze 56 articles published from 2000 to 2021.

Knowledge sharing is positively linked to organizational performance. Further, employees’ negative attitudes toward a reward system negatively relate to knowledge sharing behavior. Furthermore, management’s lack of knowledge of employees’ preferences regarding rewards leads to the provision of incorrect rewards that do not enhance knowledge sharing behavior. Finally, a conceptual model depicting the linkages among the variables under consideration has been presented.

Through the present study, employees’ attitudes toward rewards and leadership’s knowledge of employees’ preferences have been presented as critical factors that can lead to the failure of some rewards to induce knowledge sharing behavior. Further, the conceptual framework that can guide managers and leaders in strategizing on how best to develop and implement correct reward systems has been presented.

The present study is a significant contribution to the literature by focusing on the negative side of rewards toward knowledge sharing behavior with a focus on employees’ attitudes and leadership’s awareness of employees’ preferences regarding rewards.

This study proposes a novel method utilising a speech-word pair bipartite network to examine the correlation structure between members of parliament (MPs) in the context of the UK- China relationship.

We construct MP-word pair bipartite networks based on the co-occurrence relationship between MPs and words in their speech content. These networks are then mapped into monopartite MPs correlation networks. Additionally, the study calculates correlation network indicators and identifies MP communities and factions to determine the characteristics of MPs and their interrelation in the UK-China relationship. This includes insights into the distribution of key MPs, their correlation structure and the evolution and development trends of MP factions.

Analysis of the parliamentary speeches on China-related affairs in the British Parliament from 2011 to 2020 reveals that the distribution and interrelationship of MPs engaged in UK-China affairs are centralised and discrete, with a few core MPs playing an integral role in the UK-China relationship. Among them, MPs such as Lord Ahmad of Wimbledon, David Cameron, Lord Hunt of Chesterton and Lord Howell of Guildford formed factions with significant differences; however, the continuity of their evolution exhibits unstableness. The core MP factions, such as those led by Lord Ahmad of Wimbledon and David Cameron, have achieved a level of maturity and exert significant influence.

The research has several limitations that warrant acknowledgement. First, we mapped the MP-word pair bipartite network into the MP correlation network for analysis without directly analysing the structure of MPs based on the bipartite network. In future studies, we aim to explore various types of analysis based on the proposed bipartite networks to provide more comprehensive and accurate references for studying UK-China relations. In addition, we seek to incorporate semantic-level analyses, such as sentiment analysis of MPs, into the MP-word -pair bipartite networks for in-depth analysis. Second, the interpretations of MP structures in the UK-China relationship in this study are limited. Consequently, expertise in UK-China relations should be incorporated to enhance the study and provide more practical recommendations.

Firstly, the findings can contribute to an objective understanding of the characteristics and connotations of UK-China relations, thereby informing adjustments of focus accordingly. The identification of the main factions in the UK-China relationship emphasises the imperative for governments to pay greater attention to these MPs’ speeches and social relationships. Secondly, examining the evolution and development of MP factions aids in identifying a country’s diplomatic focus during different periods. This can assist governments in responding promptly to relevant issues and contribute to the formulation of effective foreign policies.

First, this study expands the research methodology of parliamentary debates analysis in previous studies. To the best of our knowledge, we are the first to study the UK-China relationship through the MP-word-pair bipartite network. This outcome inspires future researchers to apply various knowledge networks in the LIS field to elucidate deeper characteristics and connotations of UK-China relations. Second, this study provides a novel perspective for UK-China relationship analysis, which deepens the research object from keywords to MPs. This finding may offer important implications for researchers to further study the role of MPs in the UK-China relationship.

This study proposes a novel scheme for analysing the correlation structure between MPs based on bipartite networks. This approach offers insights into the development and evolving dynamics of MPs.

Effective safety communication facilitates the sharing of relevant knowledge that helps to improve safety behaviours, such as superior hazard identification and compliance. This study aims to explore channels by which construction companies can effectively communicate health and safety (H&S) among communities of their operations.

Based on a quantitative research approach, this study addressed the knowledge gap through a cross-sectional survey of 250 contractors (comprising 155 building and 95 road contractors) involved in various projects in the Ghanaian construction industry. These contractors were selected by using a stratified simple random sampling technique. Data obtained from the survey was analysed through descriptive (i.e. frequencies, mean and standard deviation) and inferential (i.e. exploratory factor analysis) statistical analyses.

The findings from the mean scores revealed that all the 12 communication channels identified in the literature, confirmed through piloting and examined by the respondents, were important channels through which construction companies can effectively communicate H&S amongst communities of their operations. The exploratory factor analysis revealed a clustering of the 12 channels of communication into 5 components: “safety demonstration in the community”; “social media”; “mass media”; “community engagement”; and “opinion leaders”.

This study offers construction project managers the means of managing one of the major stakeholders of a construction project (the community). It provides an actionable opportunity that can be leveraged strategically to integrate community members into projects to promote synergy and local content inclusion while gaining a peaceful atmosphere to achieve their project goals.

Practically, this study provides construction project managers with a means of managing one of the major stakeholders of a construction project (the community) and also demonstrates the integration of community members into projects to promote synergy and local content inclusion. This would give construction organisations a peaceful atmosphere to accomplish their project objectives.

The social implication of this study is that the study offers society a means of creating safer Ghanaian communities by offering them the knowledge of identifying hazards and avoiding risky behaviours, creating a good safety atmosphere in these communities.

This study presents construction organisations with a unique opportunity to transfer and share novel external knowledge within a different social system (the community). It contributes to the state-of-the-art knowledge in H&S communication by providing channels through which H&S can be communicated in a developing country such as Ghana.

The study intends to evaluate the impact of inflation expectation on the performance of listed commercial banks in India during 2005–2021. Inflation expectation is considered as a direct policy tool by the policymakers for stability of the economy. The study explores how inflation expectation affects the performance indicators of the Indian banking industry while controlling for a wide range of bank-specific factors.

The study applies the generalized method of moments (GMM) on a panel sample of 27 listed bank to analyse the impact of inflation expectation on banking sector performance. The data on inflation expectation are obtained from the household inflation expectation survey introduced in India by the Reserve Bank of India in 2005. Return on assets (ROA), return on equity (ROE) and Tobin's Q have been considered as the banking performance indicators in this study.

Empirical results exhibit that inflation expectation is instrumental in deciding the banking sector's performance. Inflation expectation has been found to have a significant and positive impact on accounting-based measures of banking performance. At the same time, it shows negative impact on the marketing-based measure.

The study gives a clear picture about how inflation expectation affects the banking performance and the monetary policy of the country. The study provides crucial insights to develop strategic decisions for the Indian banking sector. The adoption of proper macroeconomic policies, taking into account inflation expectation levels, is instrumental in enhancing bank's performance and in achieving economic growth.

This study contributes to the growing body of literature on the impact of inflationary conditions on banking performance. The originality lies in capturing the role of inflation expectation solely in determining banking sector performance.

The purpose of this study is to scrutinize the connection between creativity and innovation in the context of public healthcare. This is achieved by applying the theoretical concept of employee-driven innovation (EDI) to explore employees’ perceptions of their creative engagement in innovation processes, as well as to capture the managerial implications of setting up such processes in the sector.

A critical discourse analysis (CDA) is applied as a methodological lens to capture the interaction between the macro-level production and meso-level distribution of innovation discourse (top-down), and the micro-level perception of, and response to, the same (bottom-up). This study is based on a qualitative approach and is set in the public healthcare system of the Autonomous Province of Trento, Northeast Italy. In total, 26 semi-structured interviews were conducted with 22 healthcare professionals. For triangulation purposes, observation and document analysis were also performed.

The findings of this study reveal that tensions are present between the macro-level discourses and the meso-level strategies around innovation, and the micro-level perceptions of employees’ creative engagement in innovation processes. Healthcare professionals’ creative efforts are not easily recognized and supported by top management, which in turn does not receive a framework of reference in policies acknowledging the importance of human skills and creativity in innovation processes.

That this is a single case study implies a limitation on the generalizability of its results, but the results may nevertheless be transferable to similar empirical contexts. Therefore, a multiple case study design would be preferable in future studies in order to study EDI strategies and policies across various types of organizations in the public sector. Moreover, apart from CDA, other theoretical and methodological lenses can be applied to investigate the interaction between top-down organizing and bottom-up responses to innovation.

This study contributes to the EDI literature by providing a more integrative understanding of EDI in the public sector, demonstrating the importance of scrutinizing the interactions between employees and top-level management.

Knife crime and serious violent crime (SVC) among youth has been growing at an alarming rate in the UK (Harding and Allen, 2021). Community and school-based intervention and prevention services to tackle knife crime are being developed with some evaluation; however, these are independent and of varied quality and rigour. Therefore, the purpose of this study is to record the approaches being developed and synthesise existing evidence of the impact and effectiveness of programmes to reduce knife crime. In addition, the complex factors contributing to knife crime and SVC are discussed.

A systematic approach was used to conduct this knife crime intervention evidence review using two search engines and four databases. Inclusion and exclusion criteria were applied to ensure focus and relevance. The results of searches and decisions by the research team were recorded at each stage using Preferred Reporting Items for systematic reviews and meta-analyses (PRISMA).

Some evidence underpins the development of services to reduce knife crime. Much of the evidence comes from government funded project reports, intervention and prevention services reports, with few studies evaluating the efficacy of intervention programmes at present. Some studies that measured immediate impact in line with the programme’s aims were found and demonstrated positive results.

This systematic review specifically synthesised the evidence and data derived from knife crime and weapon carrying interventions and preventions, integrating both grey and published literature, with a novel discussion that highlights the importance of outcome evaluations and issues with measuring the success of individual level interventions and their contributions to the overall reduction of violence.
